Any of you beautiful mama's taking lexapro or have taken lexapro?? I was prescribed Prozac…

Any of you beautiful mama's taking lexapro or have taken lexapro?? I was prescribed Prozac throughout my pregnancy but here lately it seemed like it just stopped working and I haven't been myself.. so my doctor prescribed me lexapro. Just wondering if it's supposed to be stronger than Prozac or if there are any crazy side affects.
